* group so that they can be included in future versions of this file.
* Please submit changes by sending them to the public Khronos Bugzilla
* (http://khronos.org/bugzilla) by filing a bug against product
* "Khronos (general)" component "Registry".
*
* A predefined template which fills in some of the bug fields can be

* See the Implementer's Guidelines for information about where this file
* should be located on your system and for more details of its use:
*    http://www.khronos.org/registry/implementers_guide.pdf
*
* This file should be included as
*        #include <KHR/khrplatform.h>
* by Khronos client API header files that use its types and defines.
*
* The types in khrplatform.h should only be used to define API-specific types.
*
* Types defined in khrplatform.h:
*    khronos_int8_t              signed   8  bit
*    khronos_uint8_t             unsigned 8  bit
*    khronos_int16_t             signed   16 bit
*    khronos_uint16_t            unsigned 16 bit
*    khronos_int32_t             signed   32 bit
*    khronos_uint32_t            unsigned 32 bit
*    khronos_int64_t             signed   64 bit
*    khronos_uint64_t            unsigned 64 bit
*    khronos_intptr_t            signed   same number of bits as a pointer
*    khronos_uintptr_t           unsigned same number of bits as a pointer
*    khronos_ssize_t             signed   size
*    khronos_usize_t             unsigned size
*    khronos_float_t             signed   32 bit floating point
*    khronos_time_ns_t           unsigned 64 bit time in nanoseconds
*    khronos_utime_nanoseconds_t unsigned time interval or absolute time in
*                                         nanoseconds
*    khronos_stime_nanoseconds_t signed time interval in nanoseconds
*    khronos_boolean_enum_t      enumerated boolean type. This should
*      only be used as a base type when a client API's boolean type is
*      an enum. Client APIs which use an integer or other type for
*      booleans cannot use this as the base type for their boolean.
*
* Tokens defined in khrplatform.h:
*
*    KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.
*
*    KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.
*    KHRONOS_SUPPORT_FLOAT is 1 if floats are supported; otherwise 0.
*
* Calling convention macros defined in this file:
*    KHRONOS_APICALL
*    KHRONOS_APIENTRY
*    KHRONOS_APIATTRIBUTES
*
* These may be used in function prototypes as:
*
*      KHRONOS_APICALL void KHRONOS_APIENTRY funcname(
*                                  int arg1,
